In this 4 and a half minute video, a demonstration of the use of the ALL-TEST Pro 2000 on a 4160 Vac, 2500 horsepower stator is performed followed by a demonstration of the use of impedance to show changes in circuit capacitance. This involved the comparison of individual ‘green’ (unvarnished) coils to VPI’d (varnished) coils. Further demonstrations will be made available in the future including of additional technologies in action.
